Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicone product manufacturing equipment, and in particular to an automatic demolding device for silicone straws. Background Technology
[0002] Most silicone soft straw products on the market are produced through injection molding and demolding. Mass production is achieved by injecting molten plastic into the mold using an injection molding machine, but demolding still largely relies on manual operation. The specific process involves manually removing the high-temperature injection-molded mold core, cooling it with an air gun, and then manually demolding the product.
[0003] This manual demolding method has obvious drawbacks. The process of removing the mold core, cooling it with an air gun, and demolding is time-consuming and laborious. It not only easily leads to human fatigue, but also poses a safety hazard of burns caused by the high temperature of the mold core. In addition, the efficiency of manual operation is low, making it difficult to meet the dual requirements of efficiency and safety for large-scale production.
[0004] Therefore, those skilled in the art have provided an automatic demolding device for silicone straws to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an automatic silicone straw demolding device. Through the coordinated operation of the demolding component, the conveying component, and the heating component, it effectively solves the problems of existing technologies that rely on manual labor for silicone straw demolding, are inefficient, and pose safety hazards. It achieves automated operation of silicone straw demolding, reduces labor intensity, improves production efficiency, and ensures operational safety.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An automatic demolding device for silicone straws includes a frame, a demolding assembly, a conveying assembly, a heating assembly, a material box, a grating, and a protective cover. The frame is a horizontally arranged frame structure, and the demolding assembly, conveying assembly, heating assembly, and material box are all fixedly connected to the upper end of the frame by bolts.
[0008] The stripping assembly includes a first base plate, a motor body, a coupling, a screw, a guide rail, a tank chain, an air-blowing stripping rod, a first cylinder, a stripping push plate, a second cylinder, a stripping upper mold pressure plate, a stripping lower mold, a limit block, a first mold base, and a limit post. The first base plate is bolted to the upper end of the frame. The motor body is bolted to one end of the first base plate. The output shaft of the motor body is fixedly connected to one end of the screw via a coupling. The other end of the screw is rotatably connected to the first base plate via a bearing seat. The guide rail is fixed to the upper end of the first base plate with screws and is parallel to the screw. One end of the tank chain is fixedly connected to the first base plate with a buckle. The other end of the tank chain... The end is fixedly connected to the bottom of the stripping push plate. The stripping lower die is fixedly set on the upper part of the first base plate near the screw by bolts. The limiting block and the limiting post are both fixedly set on the stripping lower die by screws. The first die is set on the upper end of the stripping lower die and is limited by the limiting block and the limiting post. The second cylinder is fixedly set on the top of the first base plate by cylinder bracket bolts. The piston rod end of the second cylinder is fixedly connected to the top of the stripping upper die pressure plate by bolts. The stripping upper die pressure plate is located directly above the stripping lower die. The first cylinder is fixedly set on one side of the stripping push plate by bolts. The piston rod end of the first cylinder is fixedly connected to one end of the air-blowing stripping rod. The other end of the air-blowing stripping rod faces the first die.
[0009] Through the above technical solution, the motor body drives the screw to rotate through the coupling, and the guide rail enables the stable movement of the ejector plate. The tank drag chain moves with the ejector plate to protect the internal cables and air pipes. The limit block and limit post ensure that the first mold is fixed in position on the lower ejector mold to avoid displacement during demolding. The second cylinder drives the upper ejector mold pressure plate to descend and press against the lower ejector mold to form a sealed space. The first cylinder pushes the air-blowing ejector rod to align with the first mold, and blows the silicone suction tube off the mold core by blowing air, replacing the manual air gun for demolding. This greatly reduces the labor intensity of manual labor, avoids the risk of burns caused by manual contact with the high temperature mold core, and improves demolding efficiency and stability.
[0010] Furthermore, the conveying assembly includes a connecting plate, a fixed upright plate, a connecting upright plate, a third cylinder, a horizontal plate, a fourth cylinder, a clamping plate, and a fifth cylinder. The connecting plate is fixedly connected to the first base plate by bolts. The fixed upright plate is perpendicular to the connecting plate and fixedly connected to the connecting plate by bolts. The connecting upright plate is fixedly connected to one side of the fixed upright plate by bolts. The third cylinder is fixedly connected to the connecting upright plate by a cylinder bracket. The piston rod end of the third cylinder is fixedly connected to the top of the horizontal plate by bolts. The fifth cylinder is fixedly mounted on the horizontal plate by bolts. The piston rod end of the fifth cylinder is fixedly connected to one side of the fourth cylinder. The piston rod end of the fourth cylinder is fixedly connected to one side of the clamping plate. The third, fourth, and fifth cylinders are all connected to an external air pump through air pipes, and each air pipe is equipped with a solenoid valve. The solenoid valve is electrically connected to the equipment control system.
[0011] Through the above technical solution, the connecting plate, the fixed upright plate and the connecting upright plate constitute a stable support frame for the handling component. The control system controls the extension and retraction of the third cylinder through the solenoid valve to adjust the height of the horizontal plate and the lower clamping plate to adapt to the clamping position of the product after demolding. The fifth cylinder drives the fourth cylinder and the clamping plate to move horizontally, realizing the switching of the clamping plate position above the product and above the material box. The fourth cylinder drives the two clamping plates to open and close, completing the product clamping and release, realizing the automatic handling and collection of the product after demolding, without the need for manual product transfer, further improving the degree of production automation, reducing manual intervention, and reducing product damage or efficiency fluctuations caused by manual operation.
[0012] Furthermore, the heating assembly includes an upper plate body, a brass heating upper plate, a support column, a lower plate body, a second base plate, a sixth cylinder, a slide rail, a seventh cylinder, a brass heating lower plate, a second mold, a heat-insulating mica front plate, and a heat-insulating mica side plate. The upper plate body is fixedly connected to the lower end of the frame by bolts. The slide rail is fixedly mounted on the upper end of the lower plate body by screws. The bottom of the brass heating lower plate is slidably connected to the slide rail via a slider. The sixth cylinder is fixedly mounted on the top of the second base plate by bolts. The piston rod end of the sixth cylinder is fixedly connected to the lower plate body. The support column is fixedly connected between the upper plate body and the second base plate. The lower plate body slides... The upper brass heating plate is mounted on a support column and is fixed to the center of the bottom of the upper plate body by bolts and located above the lower brass heating plate. The second mold is set on the top of the lower brass heating plate. The heat-insulating mica front plate is fixed to one end of the lower plate body by screws. The heat-insulating mica side plates are fixed to both sides of the lower plate body by screws. The seventh cylinder is perpendicular to the sixth cylinder and is fixed to the upper end of the lower plate body by bolts. The piston rod end of the seventh cylinder is fixedly connected to the lower brass heating plate. Both the sixth and seventh cylinders are connected to an external air pump through air pipes, and each air pipe is equipped with a solenoid valve, which is electrically connected to the equipment control system.
[0013] Through the above technical solution, the support column connects the upper plate body and the second bottom plate, providing stable support for the heating component. The lower plate body slides along the support column to adjust the overall height. The control system controls the extension and retraction of the sixth cylinder through the solenoid valve, driving the lower plate body and the brass heating lower plate to move to adapt to the pick-up and put-out position of the second mold. The seventh cylinder drives the brass heating lower plate to slide along the slide rail, adjusting the relative position of the second mold and the brass heating upper plate to ensure uniform heating. The brass heating upper plate and the brass heating lower plate preheat the second mold after stripping, shortening the heating time during subsequent injection molding and improving the efficiency of the injection molding cycle. The heat-insulating mica front plate and side plate reduce heat loss and energy consumption, while preventing high temperature from being transferred to other components, protecting the equipment structure and extending the service life of the components.
[0014] Furthermore, both the first cylinder and the second cylinder are connected to an external air pump via air pipes, and each air pipe is equipped with a solenoid valve, which is electrically connected to the equipment control system.
[0015] Through the above technical solution, the control system can precisely control the extension and retraction timing and stroke of the first and second cylinders through solenoid valves, realize the automated control of the position adjustment of the air blowing stripping rod and the pressing or separating action of the stripping upper mold plate, ensure that the actions of each stripping component are coordinated, avoid the lag or error of manual operation, improve the accuracy and stability of the demolding action, ensure that each demolding process can be reliably completed, and reduce demolding failure or product damage caused by uncoordinated actions.
[0016] Furthermore, heating wires are embedded inside both the upper and lower brass heating plates, and the heating wires are electrically connected to an external power supply and a temperature controller.
[0017] Through the above technical solution, the temperature controller can accurately adjust the heating power of the heating wire according to production needs, thereby controlling the temperature of the upper and lower brass heating plates. This ensures that the preheating temperature of the second mold is always within the optimal range for the injection molding process, avoiding problems such as mold core damage due to excessively high temperatures or insufficient injection cycle due to excessively low temperatures. This improves the controllability and safety of the heating process, ensures the stability of the production process, and ultimately improves the molding quality of silicone straw products.
[0018] Furthermore, the grating is fixedly installed at the entrance of the protective cover by screws, and the grating is electrically connected to the equipment control system;
[0019] Through the above technical solution, the grating forms an invisible safety detection barrier. When an operator's limb accidentally enters the equipment operating area inside the protective cover, the grating immediately sends a signal to the control system. The control system quickly cuts off the equipment's power source, causing the equipment to stop operating and preventing moving or high-temperature parts from causing harm to the human body. This forms a reliable safety protection mechanism, ensuring the personal safety of operators and meeting the requirements of safe production standards.
[0020] Furthermore, two clamping plates are provided, and the two clamping plates are symmetrically distributed on both sides of the fourth cylinder;
[0021] Through the above technical solution, the two symmetrically distributed clamping plates can be simultaneously clamped from both sides of the product under the drive of the fourth cylinder. Compared with single-sided clamping, the clamping force can be applied more evenly, avoiding deformation or slippage of the product due to uneven force, ensuring the stability and integrity of the product during the handling process, reducing the damage rate of the product during handling, improving the product qualification rate, and at the same time, the symmetrical structure makes the clamping action more stable and extends the service life of the clamping plates.
[0022] Furthermore, the protective cover is rotatably connected to the outside of the frame via a hinge;
[0023] Through the above technical solution, the protective cover can be opened and closed flexibly around the hinge. When the equipment is running normally, the protective cover is closed to isolate the operating parts of the equipment from the external environment, preventing operators from accidentally touching the operating parts. When the equipment needs maintenance, repair or malfunction, the operator can easily open the protective cover and quickly access the internal parts of the equipment, improving the convenience of maintenance and repair, reducing equipment downtime and ensuring production continuity.

[0039] Working principle: After the equipment is started, the operator places the first mold 21 with the silicone suction tube on the lower mold 19 of the stripping assembly 2. Positioning is achieved through the limiting block 20 and the limiting post 22. The motor body 9 drives the screw 11 to rotate via the coupling 10, which, in conjunction with the guide rail 12, drives the stripping push plate 16 to move, aligning the air-blowing stripping rod 14 driven by the first cylinder 15 with the first mold 21. Simultaneously, the second cylinder 17 drives the upper mold pressing plate 18 to descend and press against the lower mold 19 to form a sealed space. The air-blowing stripping rod 14 blows air to detach the silicone suction tube from the first mold 21. After demolding, the third cylinder 26 of the conveying assembly 3 adjusts the height, and the fifth cylinder 30 adjusts the horizontal position, so that the two opposing cylinders driven by the fourth cylinder 28... The clamping plate 29 picks up the product and then transports it to the material box 5 for release. The second mold core 40 after being unloaded is transferred to the brass heating lower plate 39 of the heating component 4. The sixth cylinder 36 and the seventh cylinder 38 work together to adjust the position of the second mold core 40. The brass heating upper plate 32 and the brass heating lower plate 39 (with internal heating wires controlled by a temperature controller) preheat the second mold core 40. After preheating, the second mold core 40 is sent to the injection mold for secondary injection molding. Throughout the process, the protective cover 7 provides protection by closing the hinge. The grating 6 detects in real time. If any limb enters, the control system is triggered to stop the machine. The actions of each cylinder are precisely controlled by the control system through solenoid valves, forming a fully automated cycle of silicone suction tube demolding, transportation, and mold core preheating.
